Ātmakūr, nestled in the Nellore district of Andhra Pradesh, India, occupies a relatively flat terrain at approximately 14.6167°N latitude and 79.6167°E longitude. The city’s geography is dominated by the Penner River basin, influencing local climate and drainage patterns. Situated inland, it lacks the moderating influence of a large body of water like the Bay of Bengal, which lies roughly 80km east. The surrounding landscape is primarily agricultural, characterized by paddy fields and horticultural crops, with pockets of scrubland. Ātmakūr functions as a regional market town, serving the agricultural hinterland. While not a major industrial hub itself, its proximity to industrial areas further north along the Chennai-Kolkata corridor contributes to regional air pollution transport. The urban-rural gradient is fairly sharp; the city centre is densely populated, transitioning quickly to agricultural land. This proximity to agricultural practices introduces potential sources of particulate matter from crop residue burning and fertilizer application. The relatively low elevation and limited natural ventilation, coupled with seasonal temperature inversions, can trap pollutants, exacerbating air quality concerns. Dust from unpaved roads and construction activities also contributes to localized pollution, particularly during the drier months. Understanding these geographical factors is crucial for addressing Ātmakūr’s air quality challenges.

Ātmakūr experiences a tropical climate with distinct wet and dry seasons. Air quality generally deteriorates during the dry season (November to May), peaking in March and April. This is due to lower rainfall, increased dust from agricultural activities and construction, and temperature inversions trapping pollutants near the ground. The lack of monsoon winds during this period prevents dispersion. The southwest monsoon (June to September) brings significant relief, washing away pollutants and improving air quality. However, increased humidity can also foster fungal growth, potentially impacting respiratory health. October and early November see a transitional period with moderate pollution levels. Post-monsoon, crop residue burning for the next planting season contributes to a temporary spike in particulate matter. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the peak dry season months. During the monsoon, while air is cleaner, precautions against waterborne diseases are essential. Fog formation during cooler mornings in winter can also trap pollutants, requiring extra vigilance. Overall, the wet season offers the most favourable conditions for outdoor activity, while the dry season demands increased awareness and protective measures.
